Smart valve positioners are used in a variety of applications, but what are their key features? Let’s take a look.
1. Excellent Control: Two-way digital communication enables all valve information to be transmitted to the control room. Consequently, process control can be based on comprehensive valve data, effectively preventing a wide range of operational issues.
2. Enhance reliability: Information can be acquired either from field junction boxes or terminal boards, or via handheld programmers, PCs, or system workstations in the control room, thereby eliminating the need to perform operations in hazardous environments.
3. Environmental Protection: The valve leak detector is connected to the terminals of the valve controller to safeguard the on-site wiring; however, this protection has a limit. If that limit is exceeded, the device will trigger an alarm, thereby ensuring that the surrounding environment is effectively protected.
4. Reduced hardware costs: When using smart valve positioners in integrated systems, the smart valve controller replaces the traditional control regulator, thereby lowering both hardware and installation expenses and cutting wiring investment by 50%, as well as reducing expenditures on terminals and other components. In addition, the instrument employs a two-wire power supply, eliminating the need for separate, costly power cables; it can thus replace existing analog instruments equipped with valves, saving the high costs associated with laying dedicated power and signal cables.
